Solution for the material blockage of crusher
2014-12-27
The material blockage is common in the working process of crusher, and this phenomenon is caused by shutdown of motor with over load. Normally, there are two reasons for the shut of motor:
1.The belt conveyor can not meet the big capacity of crusher;
2.The downstream machine is shut down, but the crusher is on. That's to say, start the crusher before the worker should remove the whole materials from the crusher, that will waste your 3-4 hours and energy.
The running current of heavy conveyor is related with the number of materials in the lower crushing chamber of crusher, and inferior vena body caused more crusher jump stop plate conveyor of the peak current is more than a fixed (38), no-load current is a fixed value (18) a. So according to the current characteristics of plate conveyor. Developed solutions, namely in the crusher pour material install a bell mouth and alarm flashing lights, and attached directly to the relay in electric cabinet, when the plate conveyor reaches a set current value (a) 33, relay or absorption, alarm lights start flashing, bell rings.If the downstream equipment jump stop, plate conveyor current is zero, audible and visual alarm will have prompt. The driver of the car will stop pouring material into the crushing chamber, so as to prevent plugging material.
Set of plate conveyor alarm current value should be appropriate, not too low or too much. If too low, crusher is short of materials, and stone will hit plate conveyor; if too high, inferior vena material more volume, buffer space is not enough, if the downstream equipment failure is easy to cause the crusher plugging material. After a lot of validation, it shows 33A value which guarantee the stable and continuous feeding for crusher, also leaves the crusher inferior vena body enough buffer space, can effectively prevent plugging material.
